Geological hazard analysis and remediation in Xiaoqinling Gold District
As the shafts in Xiaoqinling Gold District gradually close,it has become imperative to conduct geological hazard investigations and implement remediation measures.Based on the geological environment of the mining area,this study analyzes the types of geological hazards in the region and implements targeted remediation measures,such as waste residue cleaning and transportation,construction of protective dikes,debris retention dams,debris retention walls,trench rehabilitation,road repairs,and vegetation restoration.In Xiaoqinling Gold District,28 800 m3 of debris retention walls were constructed,stabilizing 20.02 million t of ore residue,cleaning and transporting 5.84 million t of residue,leveling 1.435 million m2 of residue slopes,constructing 21.2 km of drainage channels along residue slopes,clearing and dredging 15.5 km of river channels,planting 807 000 saplings,and sowing 14.6 t of grass seeds.The environmental benefits have been significant,providing valuable insights and references for similar geological hazard remediation efforts.
